(di aio-fiom 'it may concern.' fe it known that if, KARL Komen a aubiect otV the iing of Hungary, resid indapest, Hungary, have invented iowi" is a specincation.

' invention has particolar reife." to a ro y grate, particularly adapted r r use s producers utilizing brown eoais and ite-e, comprising severa. indepene ntiyrotatabie sections, and means for rotating;

sections at diierent speeds. A

ln gasijying iignites and' brown coals with itreat content of ashes and producing innen slag', gratos heretofore devised and used do not stolto to 'the necessary extent the forming cap ot slag', which necessitates lrnoclr w the cap occasionally .by the use vantageonsly adects the production ot gas,a

Acc ng to this invention, the rotary milling-grate, serving as the bottom of the gas-producer, comprises @axially-arranged, independently-rotatable substantially conical sections rotatable in either direction, thus preventing the formation of a cap of Slag, and avoidii'ig the objection noted above.

The invention also resides in certain speoiiic improvements in the pear in the following descr struction thereof.

The accompanying drawing;` preferred which* .Figure l is a contrai discloses the embodiment ot tne invention, 1n

vertical sectionai Figure 2 is a top plan view thereof,

Referring, now, in detail, 'to the drawing:

fi designates the slag-plate ot the gas producer. y"lhe slag-plate is substantiaily truncated conelshaped, as shown, and Ais preferably provided, at its lower end, with an annular, circumferential, horizontal, basal tlange o, resting upon anti-frictional ball-bearings b in the `annular groove ot a traek-ring o2.

Secured. to the fian e Z) at its outer or :tree circumferential e ge is a--toothed 'ring Z8, meshing with a screw S3 on a rotatable shaft a rotatabiy driven Jfrom any suitable source oi power.

Carried bythe tiange b, on top thereof,

this naturally disad-` upward and outward 'P b3 having, at its top, a cirdownward-inclined riin bt, al slagiplate A is provided, at an opening o, through which extend the supporting stems C and B of the i ate-sections- The stern C may, if desired, be in two secas sbown in the drawing,a relasection and a short section, C, on", and the latter, as well as the tial-ing; upper portion b5 of the stern B being provided with side openings d, The stem B iares outward toward the top and bottom thereof, as shown at b5,- Z', respectively,- the flaring portion b5 supporting the grateeection B, which, as shown, is a substantially truncated conoidal member, provided with transverselyextending longitudinally curved shearing blades b" on its' upper surface. The flaring portion be terminates, at its bottom, in a basal, annular, horizontal iiange bs having, on its perimeter worm-teeth Z meshing with a worin S rotatably driven from any suitable source of power,4

'Ehe stem C is provided, at its bottom, with a correspondingly outward-flared portion cX terminating in a corresponding basai, annular, horizontal flange c2 provided., on its perimeter, with worm-teeth Z2 meshing with a worin S2 driven from any suitable source of power.

Between the basal kflanges o8 and o2 between the. latter and a bed-plate X disposed anti-friction ball bearings b9.

As shown, the stemsl B and C are concentric and telescopically arranged, and have, as their axis of rotation, a vertical shaft or axle Y resting, at its bottom, in a depending, hollow stein of the bed-plate X.

The shorter section c ot the stem C depends :troni and supports the conoidai gratesection c, which is of a dimension to extend over the top, contrai opening I). in tbe Jerrate E.

IThe grate c terminates, at its top, in an upwardprojocting; hollow nose c having side openings c3 and covered by a cap c4, which projects beyond the side wall oir the nose, as shown. The grate c is provided with transverselyextending ribs D7 on its upper surface.

As shown, the grate sections B and c Inav be annular inciined and are

titi

Sti

are disposed in different horizontalA planes, i. e., they `are disposed in superpose'd rela# i `displacefthe slag outwardly.

The stem B is provided, toward its top, with side openings d, which serve for the supply of air, as do, also, the openings o5 beneath the grate-section c and the corresponding openings 03 beneath the hood or cap 04.

yihe slag-plate A preferably has, on its top surface, transversely extending ribs A.

it will now be noted that, by the construction described, the grate-sections may be ro tated in either direction at diierent speeds. The number of the grate-sections may be varied, according to requirements, and, while have she-wn two of such sections, more may be used, obviously, if required.

The reiative speeds or' the grate-sections prevent the formation ofy vslag-caps, as distinguished from the constructions known to me, in which the formation of slag has been promoted by the decrease of the revolving speed from the periphery to the center of the grate.

Having thus fully described my invention, what I claim as new and desire to secure by Letters-Patent is:

A rotary grate for gasproducers,co1npris ing a plurality of substantially conical, superposed, co-axial grate-sections independently rotatable in either direction, each of said grate-sections being provided on its upper surface with transversely-extending, longitudinally-curved shearing-blades.

ln testimony whereof l have signed my name to this specification in the presence of two subscribing witnesses.
